Genes affected

LDLR (HGNC:6547): (low density lipoprotein receptor) The low density lipoprotein receptor (LDLR) gene family consists of cell surface proteins involved in receptor-mediated endocytosis of specific ligands. The encoded protein is normally bound at the cell membrane, where it binds low density lipoprotein/cholesterol and is taken into the cell. Lysosomes release the cholesterol, which is made available for repression of microsomal enzyme 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase, the rate-limiting step in cholesterol synthesis. At the same time, a reciprocal stimulation of cholesterol ester synthesis takes place. Mutations in this gene cause the autosomal dominant disorder, familial hypercholesterolemia. Alternate splicing results in multiple transcript variants.[provided by RefSeq, May 2022]

All of Us Research Program, National Institutes of Health

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This missense variant (also known as p.Asn309His in the mature protein) replaces asparagine with histidine at codon 330 of the LDLR protein. Computational prediction tools and conservation analyses are inconclusive regarding the impact of this variant on the protein function. Computational splicing tools suggest that this variant may not impact RNA splicing. In a high-throughput LDL uptake assay, this variant has been determined to be non-disruptive to LDLR function (PMID: 25647241). To our knowledge, this variant has not been reported in individuals affected with familial hypercholesterolemia in the literature. This variant has been identified in 6/282428 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -

Collection Method:clinical testing

This missense variant replaces asparagine with histidine at codon 330 of the LDLR protein. This variant is also known as p.Asn309His in the mature protein. Computational prediction suggests that this variant may not impact protein structure and function. In a high-throughput LDL uptake assay, this variant has been determined to be non-disruptive to LDLR function (PMID: 25647241). To our knowledge, this variant has not been reported in individuals affected with LDLR-related disorders in the literature. This variant has been identified in 6/282428 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -
